   single: symbol table

Names for built-in exceptions and functions and a number of constants are found

in a separate  symbol table.  This table is searched last when the interpreter

looks up the meaning of a name, so local and global user-defined names can

override built-in names.  Built-in types are described together here for easy

reference.

The tables in this chapter document the priorities of operators by listing them

in order of ascending priority (within a table) and grouping operators that have

the same priority in the same box. Binary operators of the same priority group

from left to right. (Unary operators group from right to left, but there you

have no real choice.)  See :ref:`operator-summary` for the complete picture on

operator priorities.
